研究了北美西部地震的强震资料，为估计峰值加速度、速度和位移随距离的变化提供了依据，这三个震级分别为5.0到5.7、6.0到6.4和7.1到7.6级。对圣费尔南多地震资料的分析表明，小型建筑物地基上记录的水平加速度、速度和位移峰值与大型建筑物地基上记录的水平加速度、速度和位移峰值之间存在着微小但在统计上显著的差异。大结构底部的峰值加速度比小结构底部的加速度峰值小，峰值速度和位移大。在回归分析所用的距离范围内(15至100公里)，在圣费尔南多地震中在土壤场地记录的峰值水平加速度与在岩石场地记录的峰值水平加速度值没有显著差异，但在土壤场地记录的峰值水平速度和位移值显著大于在土壤场地记录的峰值水平加速度
Strong-motion data from earthquakes of western North America are examined to provide the basis for estimating peak acceleration, velocity, and displacement as a function of distance for three magnitude classes, 5.0 to 5.7, 6.0 to 6.4, and 7.1 to 7.6. Analysis of a subset of the data from the San Fernando earthquake shows that small but statistically significant differences exist between peak values of horizontal acceleration, velocity, and displacement recorded on soil at the base of small structures and values recorded at the base of large structures. The peak acceleration tends to be less and the peak velocity and displacement to be greater at the base of large structures than at the base of small structures. In the distance range used in the regression analysis (15 to 100 km), the values of peak horizontal acceleration recorded at soil sites in the San Fernando earthquake are not significantly different from the values recorded at rock sites, but values of peak horizontal velocity and displacement are significantly greater at sol
